To all whom it may concern:

Be it known that 1, WILLIAM H. Rose, a citizen of the United States, andresiding at Jersey City, Hudson County, State of 5 New Jersey, haveinvented certain new and useful Improvements in Package Closures, ofwhich the following is a specification.

This invention relates to closures for receptacles made of paper orother fibrous material.

It is the object of the invention to provide a metal closure which canbe easily and quickly applied to a paper or other similar receptaclewithout the. use of tools -or machinery involving complicated mechanicaloperations and one which when, in position will be firmly secured to thebody of the receptacle and practically non-' removable withoutdestruction of the re: ceptacle itself. 'The invention viewed in a morelimited aspect further aims to provide a closure which is so shaped asto support the wall of the receptacle against inward pressure so thatcrushing or mutilation of the receptacle at the ends thereof isprevented. Cther novel and valuable features of the invention willhereinafter appear.

The invention may be embodied in closures which differ in form and whichare ca 1| able of use in different relations and for di 1i? erentpurposes. In the drawings accompanying this specification and forming apart thereof T have, therefore, illustrated the in'ven tion applied tovarious forms of receptacles and closures. Tn the drawings: 'Fig. 1 is aview in elevation showing the closure applied on one end of a paperbottle, I

carton or the like; I Fig. 2 is a vertical sectional view of the todevice of Figure 1 showing the construction of one form of my improvedclosure and its relation to the part of the receptacle to which it isapplied;

Fig. 3 is a sectional viewshowing my im- Referring to the drawings indetail the numeral 10 represents in each of the figures t5 the body ofthe receptacle to which the Fig. 4: is a vertical sectional, view of apor--- closure is applied, such body being made of paper or otherfibrous material and having a straight wall to receive the closure orclosures applied thereto. The body of the receptacle, as shown in thevarious figures of the drawing, is made cylindrical although othershapes of body may be employed.

In the construction illustrated in Figures 1 and 2 the numeral 11generally designates the main body or central" portion of the closurewhich is formed with an opening in which a removable friction cover 16is inserted; Aroundthe' central portion 11 in this form of my improvedclosure there is provided an inner wall 12 and an outer wallor flange18, these walls being preferably of substantially the same lengthandextend ing some distance beyond the plane ofthe central portion 11 ofthe closure. The wallsprefer- 'ably made by striking up or indenting thematerial of the wall, such prongs pointing toward the base of the flange13 or toward the bottom of the pocket formed between the walls 12 and13. The prongs arebent inwardly or toward the wall 12 to a slightextentso that they will be compelled to engage and embed themselves in thematerial come prising the wall of the receptacle when the an closure'isforced into position.

Tn Figure 3 of the drawing there is shown a receptacle having myimproved closures applied to each end thereof, such arrange ment beinguseful in mailing tubes or any other construction where it is desired toapply both a top and a bottom to a paper-tube; Different forms ofclosure are shown at the two ends of this figure, it being evident ofcourse, that any of the various forms of clo-x roe sures hereinillustrated may be used on the ends of the tube shown in this figure.The closure shown at the-right hand portion of Figure 3 is substantiallythe same as that illustrated in Figure 2, except that the centralportion 11 thereof is not providedwith an opening. This closure isprovided with an inner wall 12 and an outer wall 13, the latter havingon its inner surface prongs 15 substantially the same as shown in Figurelie 2. The form of closure shown at the left hand portion of Figure 3comprises a body or central portion 11 which is provided with a wall orflange 13 similar to the wall] 13 shown in Figure 2, this wall 13 beingprovided on its inner surface with projections 15 substantially the sameas those shown in the otherform of the invention.

' In this'for nof closure I dispense with the .themselves in the wal1o1f;. the receptacle and.

this form of device the closure is alsoproivided with an inner wall 12and an outer wall 13 between which there is formed a pocket for thereception'of'the end of the receptacle, the outer wall 13? beingprovided with prongs 15 which arei adapted to embed prevent removalof'Fth'e. closurethereform.

It is apparent' that-giny improved closure can be easily applied-to apaperreceptacle by merely forcing the closure on the receptacle. Notool's-{or machinery are necessary for this operatiomiand it is'furtherapparent that when employed in-the form shown in Figures2'. and 4 andatthe ri ht hand portion of Figure'3,'the wall of t e receptacle will be]braced against external pressure so that crushing or mutilation of thesame will not take place.

Furthermore it will be understood that the various forms of my improvedclosure when applied to a receptacle will be firmly secured thereto,this result being accomplished in each case by the prongs on the outerwall or flange engaging and embed-- ding themselves in the materialforming the wall of the receptacle. A closure construct.- ed in eitherof the ways above described will, therefore, be practically nonremovablewhen once applied to a receptacle since it becomes necessary to tear ormutilate the paper of the receptacle in order to detach the closurethere-from. On account of this secure fastening of the closure to thereceptacle, my improved device is of value where a permanent closure isdesired for a paper receptacle with or without an opening, and alsowhere as shown in Figure 4, it is desired to provide a closure whichwill permit use of the contents of the receptacle and at the same timeprevent refilling of the same.

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is;

1. A construction of the kind described comprising a receptacle having astraight wall of paper or other fibrous material, a nonremovablemetallic closure therefor having a body portion and a straight flangeintegral with the body portion, said flange being shaped to surround andclosely fit said wall, said flange having a series of intc gralprojections on the inner surface there of extending toward the base ofthe flange for engaging in the material of the wall and permanentlholding the closure in position when orced on the receptacle.

2. A receptacle having an opening surrounded by a straight wall composedof fibrous material, a metallic closure mounted in said opening, saidclosure having a central portion lying within the wall of thereceptacle, a straight wall on said closure extending outwardly from thecentral portion thereof and contacting with the inner wall of thereceptacle, an outer straight wall or flange on said closure spaced fromthe inner wall thereof and engaging the outer wall of the receptacle,whereby a pocket is formed between the walls of said closure in whichthe wall of the receptacle is inserted and held, one of the walls ofsaid closure having a series of integral prongs extending toward thebottom of said pocket for engaging in the fibrous material forming thewall of the receptacle to prevent removal of the closure from thereceptacle.

In testimony whereof I aflix my signature.
